BEAN-SEPARATOR.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed April 17, 1913. Serial No. 761,775.

To all whom it may concern:

Be it known that I, WILLIAM EDWIN CLARKE, a citizen of the United States, re-

siding at Brown City, in the county of Sanilac and State of Michigan, have invented a new and useful Bean-Separator, of which the following is a specification.

This invention relates to a bean separator and more particularly to a separator including a plurality of rolls arranged in pairs and upon which rolls the beans are disposed, whereby the smooth surface of the good beans will not be affected by the rotating of the rolls and will remain thereon while the poorer beans with the rough or mutilated surfaces will cling to the sides of the rolls and be removed therefrom.

An object of the present invention is to provide an improved form of bean separator for separating the good and bad beans, the poorer quality or bad beans being discarded and the better quality or good ones being discharged into a delivery spout.

A further object is to provide a plurality of rotating rolls arranged in pairs and revolving in opposite directions and outwardly from the contacting line, and to provide an angular slot in the side walls of the receptacle whereby the rolls will automatically be held in resilient contact.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts and in the details of, construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 is a top plan view of my improved machine. Fig. 2 is a fragmental view in elevation thereof. Fig. 3 is a perspective view of one of the separating rolls. Fig. 4 is a plan view of the textile material with which the rolls are covered. Figs. 5 and 6 illustrate in perspective the means whereby the textile material is detachably secured to the said rolls. Fig. 7 is a cross sectional view taken on the line A-A of Fig. 3.

Referring to the drawings in which similar reference numerals designate correspondmg parts throughout the several views, 1 is a box or receptacle provided with the upstanding side walls 2 and which side walls provide supporting means for the separating rolls. The front wall 2 is disposed a slight distancebelow wall 3 so that the separating rolls 4 are disposed at a slight angle to the horizontal in orderxthat the beans which are fed into one end of the roll will gradually travel toward the front or delivery end thereof.

As illustrated in Fig. 2 of the drawings the walls 2 and 3 are provided with a vertical slot 5 and an angular slot 6, journaled within which slots are the outstanding trunnions 7 of the separating rolls 4. The trunnions 7 are provided with a shoulder 8 adj aoent their inner ends, which shoulder is adapted to hold the rolls in spaced con tact with the walls 2 and 3 of the box or receptacle 1. The trunnions 7 are adapted to fit down into the slots 5 and 6 which are provided in the walls 2 and 3 and which slots are arranged in pairs so that the separating rolls will be arranged in pairs, each pair constituting a complete separating means for the beans. One trunnion of each pair of rollers and preferably the trunnion of the roller which fits within the vertical slot 5, is provided with pulley wheels 9 thereon, extending between which are suit able belts 10, the power being supplied to the first roll by a power driven belt-11.

From the foregoing it will be apparent that one roll of each pair is power driven and the other roll of each pair which fits within the inclined, slotis adapted to frictionally contact therewith and to be rotated thereby, the result being a smooth and flexible operation of the entire machine. By making the various rolls belt driven it allows a certain resiliency or flexibility to be imparted to the rolls whereby any unevenness of drive will be taken up, thereby preventing jerks such as due to sudden stops and starts which would tend to eject the good beans as well as the had over the sides of the rolls. Disposed at the lower end of each pair of rolls is a delivery spout 12 which is adapted to receive the good beans as they pass beyond the ends of the rolls. The said spouts are adapted to deliver the said beans into suitable receptacles posi tioned therebeneath. The said outlet or the level of the rear.

delivery spouts are positioned below and in alinement with the meeting portions of the two rolls. i i

As illustrated in Figs. 3, 5 and 6, clips 'are'arranged at the ends of the rolls and provide'means whereby the strip of textile material may be detachably and at the same time rigidly secured to the. outer peripheral surface of the rolls. The clip at the lower extremity of the rolls is substantially L- shaped in outline as illustratedin Fig. 5 and comprises the vertical apertured portion 13 and the horizontal portion '14:

formed integral'therewith. The portion 14 is provided with a downwardly extending lip 15-which is adapted to fit within a suitable groove formedin the/"peripheral surface of the; roll 4 and which lip is adapted to engage one end of the textile strip. The 20 roll is substantially :the same as the one clip atthe upper or opposite end of the .andin orderto-provide a suitablesurface oflthe upper clip member and rigidly se-. cured thereto, it being pointed out in this connection that with the strip secured to uponthe said rolls which will engage bad. beans'and eject the same over the sides of the rolls, a textile strip such as illustrated in Fig. 4 of the drawings is provided and the same comprises the body portion 17 with the two tapered ends 18 extending therefrom. The end 18 is first inserted be-' neath the lip15 ofthe lower clip member and suitable screws are then. passed through the apertures in the vertical portion thereof, whereby the end of the textile strip will be rigidly secured to the lower end of the roll. The roll is slowly revolved to bind the textile strip 17 thereon and in a helical manner,the edges of the successive convolutions overlapping to form a continuous surface. The free endof the textile strip isthen disposed beneath the serrated lip the rolls as I have described, the beans will not come into contact with the metallic clips as the lower clip is' covered and the. beans.

' J are deposited .upon the rolls ata point he ings.

low the upper clip. The'manner in which the clip members fitwithin slots 19 in the rolls is clearly shown in Fig. of the draw- The operation of my improved bean separator and picker may be described as fol- "lows: The beans are introduced 01'' disposed upon the upper extremities of the roller pairs through a suitable tube or hopper dischargepipe 20. The good and bad beans then gradually work their way down toward the lower extremities of the pairs of rollers and the rollers are rotated as indicated by the arrows in Fig. 2, in opposite directions up and away from the line of contact of the rolls of each pair. The bad beans as has been explained, present a roughened or irregular surface and due to the surface presented by the textile material they'will be engaged thereby and discharged over the side edges of the rolls and into'the box or receptacle where they may be removed from time to time. The good beans presenting a smooth surface grad ually work their way downward to the lower discharge end of the pairs of rollers and drop upon the V-shaped delivery spout 12 where they are delivered into suitable receptacles which may be positioned therebeneath. The manner in which the various rolls are. driven and also the manner in which the rolls are supported provides that a smooth and flexible operation of the machine will be obtained and that an efficient "separating of the beans will be procured, it being understood that the machine may be used for the separation of other farm products which are of an allied nature.

Having thus fully described the invention what I claim to be new and original with me is z- A separator roller having short longitudinal groovesextending longitudinally from its ends, angular clips having certain arms fitting withinsaid grooves and their other arms being removably secured to the ends of. the roller, and a facing strip wrapped around the roller and having its ends extending under the first mentioned arms of said clips within said grooves, those edges of the first mentioned arms which project in the same direction as the ends of the strip being provided with inturned toothed portions biting the strip.

Intestimony that I claimfthe foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
